HEDDLE-ACTUATI NG MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 500,112, datedJune 27,1893.

Application filed December '7, 1892. Serial No. 454,421. (No model.)

To all whom it may concern:

Be it known that I, FLORENTIN BUYcK, a citizen of theUnited States, anda-resident of Philadelphia, Pennsylvania, have nvented certain new anduseful Improvements in Heddle-Actuating Mechanism for Looms, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part of this specification.

My invention consists in certain new and useful improvements inmechanism for manipulating a series of heddles employed in looms forweaving. V

In the accompanying drawings-Figure 1 is a front view partly in verticalsection of a portion of a loom having my invention applied thereto. Fig.2 is an enlarged vertical sectional view on line 12, Fig. 1. Fig. 3 isan end elevation of a portion of Fig. 2. Fig. 4: is an enlarged View ofa portion of the hook, its guide frame and spring. Fig. 5 is a sectionalplan view 'on the line 3-4, Fig. 4. Fig. 6 is an enlarged detail view ofthe lower end of the hook. Fig. 7 is a sectional view showing the doublecrank movement. Fig. 8 is aside elevation of the'take-up link. Fig. 9 isan end elevation of the cylinder. Fig. 10 is a side elevation thereof,and Fig. 11 is a side elevation of several cards. Y

A is the loom frame upon which is mounted the crank-shaft B, driven frompulleys Oand carrying chain wheel D adapted to rotate a counter shaft Fby means of chain wheel D, and chain E. Counter shaft F carries ancecentric G, which transmits motion to an L- shaped arm I by means of aconnecting rod H. This arm I is fulcrumed at l to the machine frameN andcarries the card cylinder J, around which pass the cards K. This cardcylinder J is intermittently rotated by means of a hook L pivoted to theframe M and adapted to engage with pins on the end of the cylinder inthe usual manner.

70 is a Wire finger projecting up from the loom frame and forming aguide for the cards.

Mounted upon the frame M is an oblong guide bracket N having a centralpartition 01, partitions n and orifices n. (See Figs. 4 and 5.)

O are a series of spring fingers hung to the bracket N by means of theorifices n.

P are the operating hooks guided in bracket N between the partitions nand having close to their upper extremities notchesp and projectingledges 19, while near their lower extremities' are the orifices 19 towhich are adapted wire hooks terminating in cords y and :20 whichconnect with the heddles W by means of the rocker bars '0 and. o, cordsX, take-up link Y and rod y.

The counter shaft F terminates at one end in a double crank F (see Figs.2 and 7) said double crank being formed preferably of an inner and outerdisk connected together and separated by a bolt set out from the centerof the shaft F forming one crank, to which is connected a rod Q. Theouter disk also has a bolt set diametrically opposite with reference tothe center of the shaft to the boltto which the rod Q is connected andis adapted to receive a rod R. Both these bolts are clamped to the disksby means of suitable nuts, and rest in slots in said disks so that thecrank movement of these bolts may be adjusted as desired. Rods Q and Rconnect these cranks with fulcrumed bars Q and R, which bars, inconjunction with fulcrumed bar S (connected by link S with bar Q)manipulate the heddles as dictated by the cylinder cards by means of thehooks P and the mechanism described. The bars Q, R and S passthrough theframe M and are guided by slots m.

U are supporting bars passing through the frame M into the wall U (orother suitable fixed structure) and carry bracket T, terminating at oneend in a bracket T having suitable slots for the reception of the barsQ, R, and S, and adjusting plates t therefor. These adjusting platescarry the fulcrum end of the bars Q, Pt and S, and may be adjustedvertically to fix the relative position of the bars Q, R and S, to anicety with respect to the notches and lengths of the operating hooks P;thus forming the fulcrum end of the bars Q, R, and S. The bracket Textends upward and forms one end of a support for the rocker bars V,While a projection of the frame M of the machine forms the othersupport.

The take-up link Y is mounted upon the end of the screw-threaded rod y,and is held in position at one end by set nuts 11 while the opposite endis adapted to receive the cords y from the two lower corners of thehooks P. This device is provided for the reason that by its adjustmentall of the heddle cords can be kept taut, and therefore, any slightmovement of the hooks is communicated immediately to the heddles. Thetwo cords at the bottom of the hooks are provided to secure themanipulation of the heddles should either of these cords break at thispoint.

The operation of the machine is as follows: The pattern desired to beproduced in the fabric by the manipulation of the hed'dles is indentedupon the cards in the usual manner and the cards placed upon thecylinder, which is journaled upon the fulcrum bracket Z and is given anintermittent rock motion by means of the eccentric G on shaft F. Thecards then '-impinge against any of the spring fingers O (as theorifices in said cards maydetermine) moving the notches p in the hooksPinto e11- gagement with the reciprocating bar R thus causing theseengaged hooks P to be recipro cated vertically with this bar R and sonecessarily the heddles W which are connected with the hooks by means ofthe cord X and other connecting mechanisms shown in Fig. 1. This actionof the heddles continues until the engaged hooks P are released fromcontact with the bar R by the spring fingers O, which in turn arereleased by the backing 0E of the cards on the card cylinder. The hooksP when released by the spring fingers drop back by their own weight tothe position shown in Fig. 1. It will be seen that the-bars Q and Stravel together by means of theconnecting link S, and that their actionis the reverse of that of the bar R by means of the double crank F-thatis to say when the bar R is moving up the bars Q and S will be movingdown so that the shed thrown by the heddles W is determined by theengagement of these hooks with either the bar R or the bars Q and S aseach heddle has its own independent hook P and each hook is controlledby the movement of the spring fingers which are acted upon by the cardsof the card cylinder as before described.

' I claim as my invention- 1. In a machine for actuating loom heddles,vertical hooks P having notches p and 13' therein close to their upperends and adapted to engage with the reciprocating bars Q and R and alsohaving orifices 12 therein at their lower ends to which are attachedsuitable cords connecting said hooks P with the heddles, said hooks alsobeing adapted to rest upon and be retainedlaterally by the reciprocatingbar S; in combination with the partition bracket N carrying springfingers 0 adapted to impinge against said hooks P and actuated byintermittently rotating cards and card cylinder, bars Q, R, and S,links, heddles W, rotating cards J and cardcylinder K therefor, doublecrank F, rods Q, and R,

and bracket '1". all substantially as and for the purposes set forth.

2. In a machine for actuating looin heddles, vertical hooks P havingnotches p and 19' therein close to their upper ends and adapted toengage with reciprocating bars Q and R and also having orifices ptherein at their lower ends to which are attached suitable cordsconnecting said hooks P with the heddles, said hooks also being adaptedto rest upon and be retained laterally by the reciprocating bar S; incombination with a partition bracket, N, carrying spring fingers 0adapted to impinge against said hooks P and actuated by intermittentlyrotating cards and card cylinder bars Q, R, and S, link S, heddlestW;rotating cards J, and card cylinder K therefor, double crank F, rods Qand R, and bracket '1" having adjustable plates for the reception of thebars Q, R, and S, all substantially as and for the purposes set forth.

In testimony whereof I have hereunto atfixed my signature inthe'pres'ence of two subscribing witnesses. Q
